SPECIFICATION forming part of Letters Patent No. 604,771, dated May 31,189.81.

" llnmion inea January s, 1897. vsans No. 618,450. (remodel.)

To all whom tm/,ty concern:

Be it known that I, ALBERT K. MMISFIELD,`

of Salem, in the county of Columbiana and State of Ohio, have invented acertain new and useful improvement in Throttle-Valves,

of which improvement the following isa specification.

The object of my invention is to provide a throttle or stop valve forcontrolling the flow `of steam or other fluid which shall be of simpleand inexpensive construction and adapted by a readily-effectedadjustment to serve either as an angle-valve or a straightway valve, asmay be desired.

The im'provemen claimed is hereinafter fully'set forth.

`ln the accompanying drawings, Figure 1 is a view' in elevation of athrottle-valve embodying my invention,the same being adjusted inposit-ion to serve as a straightway valve; Fig. 2, a vertical centralsection when adjusted to serve as an angle-valve; Fig. 3, a view inelevation and on a reduced scale of the lower section of the valve-bodydetached;

and Fig. et, a plan view, on a similar scale, of the valve memberproper.

In the practice of my invention I provide a valve-body composed of twosections l 2,which are preferably substantially hemispherical and abutby finished faces, which are inclined atan angle of preferablyforty-five' degrees to the axes of the sections and are connected bybolts 3, passing through Han ges 4t 5, which .project from the walls ofthe sections and form parts of the abutting surfaces thereof. Thesections are provided with tubu.- lar pipe connections, as a flangedpassage 6 and a threaded passage 7, respectively, at their endsfarthestfrom their abutting faces and are clamped irmly together by nuts8, engaging the threads of the bolts 3. The axes of the pipe connectionsare offset from the common centervof the two sections of the valve-body,as indicated in Fig. 2, and econrom y of space is thereby attained, as asmaller body for a given diameter of pipe may by vthis means beemployed. A transverse partition 9,. on which is formed, avalve-faceflO, is fixed to one ofithe sections of the body, as thesection 1, at the'end opposite the pipe connection, said partition beinginclined correspondingly with the abutting face ofthe section and beingin this case cast integral therewith. The valve-face projects slightlyabove the face of the partition and is in the form vof two oppositesectors, each of which incloses. a port 11 for the passage of iiuid. Inorder to provide additibnal bearing-surface for the valve, thevalve-face may beextended either entirely or partially from one sectorto the other, and in the instance shown two opposite arc-formed facesl2, which are iiush with thev segmental portions of the valve-face, areinterposed between their outer ends, the faces l2 preventing the valvemember from dropping or cantingbetween the segmental portions. A centralsupport 13 for the partition 9, exten ding therefrom to the wall of thebodysection, may be provided for the purpose of strengthening thepartition.

, .The valvememher proper, 14.conssts of a plate or disk having a nishedrimcorre? sponding substantially in diameter and width with the curvedportions of the valve-face and provided with two Vopposite sector shapedports 15, corresponding tothe ports of the partition 9. The valve member14 is'journaled'to move freely about its axis on astem 16, which isfixed centrally on the partition 9 and is provided with a segmental gear17 near its'periphery, through which movement is imparted to it from anoperating-stem 18.

The stem 18 is fitted to rotate in the other connection of said sectionand preferably passes through a properly-packed stuiiingbox 19. Ahand-Wheel 2O is secured upon the outer end of the stem 18, and a bevelpinion 2l is formed upon or fixed to its inner end, said pinion meshingwith the segmental gear 17 of the valve member 1.4: and impartingmovement theretoabout its axis in one-or the other direction to whollyor partially cover or uncover the ports 11 of the partition section 2 ofthe valve-body, with its axis aty substantially a right angle to that ofthe pipe 9 byand in accordance with the rotation in one or theotherdirection of the opera'ting-,

stem. 1 8. The pinion 21 is faced off truly on its upper side andabutsagainst a correspondingly-1inished face on the valve-body, to which itis held with'suicient pressure tomaintain a tight joint by a Vlightplate-spring 24. By

' this construction a stuiingzbox forthe valve-` stern 18 may bedispensed with,or if it be I employedv4 it may be packed while the valveis under steam. The spring 24: is in the instance shown connected by astud 25 to the stem 16 of the valve member; but such specilcI locationof its xed end is merely a matter of convenience, and it may, ifpreferred, be connected directly to the valve-body.

The valve member 14 is held with the proper degree of tightness againstthe valve-face by an elastic resistance interposed between it and theoperating-stem 18, consisting in the ,tion7 thereof assumes theverticalor the horizontal position desired, after which th'ebodysections arebolted together, andthe appliance is ready for use, the change ofvposition of the section which carries the stem involvi ing no change inthe operativen'elation of the gearing and` appliances bywhich the valvemember is moved and held in proper relation; to the valve-face. 4 A fulland direct passage for iiuid through ports of large area is provided,and the quick opening and closure of. said ports is eiected bythemultiplyinggearing through Which the valve member proper is actuated. lv

.I claim asmyi'nvention and desire to. -secureby Letters Patent- 1; Thecombination, substantially as. set forth, of a valve-body composed oftwo sec-- tions, provided, each, with a. pipe connection,

and abutting in a plane inclined: to the axis of' the valve-body, saidsections being relatively adjustablev to, form either astraightway or anangle valve, a valve-face fixed to one of said sections, a valve'ttedito'move about an axis thereon, an operating.- stern.`

whichis fitted to be rotated in the other section, at anzanglewith theabutting face thereof, and gearing through which, movement isimpartedto-t'he valve from the stem,.t he stem.

being, in each adjustment of the-valve-body' sectionsat right angles tothe. axis oitl one section, and: at right4 angles to.l the ,axesy of5,5. both sectionswhemthey areadjnsteditoiorm i a straightway valve.

2. T he combination, substantially as set forth, of a valve-,bodycomposed of two substantially hemispherical scctions,'each provided witha pipe connection the axis of which is offset from the center of thevalve-body,

and abutting in a plane inclined tothe axis v of the valve body,peripheral iianges surrounding the abutting faces of said sections,connecti 11g-bolts passing thro ugh said Han ges, a valve-'face fixed toone of said sections, a valve fitted to move about an axis thereon, astem which is rotatable in the other section,

and gearing through which movement is im-l parted to the valve from thestem.
